18 FUNCTIONS DESCRIPTION (description of the functions with access code< 3) Identification of the function (not visualized on display) MENU 1.SENSOR (POS. 1) Nominal diameter of sensor [ND= XXXX] Converter request Menu visualized on the converter ( from 1 to 11) Synthetic description of the function MENU 1.SENSOR (POS. 1.7) Autozero calibration [AUTOZERO CAL.] This function enables/disables the automatic zero calibration system. To perform the sensor it is absolutely necessary the sensor is full of liquid and that the liquid is perfectly staying still. Even very small movement of the liquid may affect the result of this function, and, consequently, the accuracy of the system. Once you are sure the a.m. conditions are fulfilled (and when the percentage flow rate value is stable) press for more than one second the key. Check the percentage flow rate value goes to zero, otherwise repeat the operation again. When the value is stable at zero, then press. (POS. 1.8) Empty pipe calibration [E.P. CALIBR.] this function enables/disables the automatic calibration procedure of the empty pipe detection function. Before enabling this function, the Empty Pipe test should be enabled first as above described. Before performing this function, the sensor has to be completely filled in with the liquid so that both the lining and the electrodes are wetted. The sensor has then to be emptied again and then you should press the key : the operation will have to be confirmed by pressing the key or cancelled by pressing the key. By this function the system sets the value of a parameter, which could also be manually changed (see function E.P.thr within the menu 4-ALARMS). MENU 2.SCALES (POS. 2.1) Full scale n 1-2 [FS1-2=dm³/SX.XXXX] Full scale value set for range N.1-2. There are four fields to fill in order to set this parameter, from left to right: 1) volume unit of measure, 2) type of unit, 3) time unit of measure and 4) numeric value. The selection is made by positioning the cursor on the field to modify. To change the type of unit of measure (metric, British or American, mass or volume) the cursor has to be positioned on the symbol / (field N. 2). When the nominal diameter is set to zero it is possible to modify only the numeric field, since the unit of measure stays at m/sec. The following tables show the units of measure available and the conversion factor by comparison with 1 dm 3 and 1 kg. The converter accepts any kind of combination of units of measure satisfying both the following conditions: Numeric field value / 25 fs max numeric field value fs max. where fs max is the maximum full scale value corresponding to the sensor, equal to a 10 m/sec liquid speed. The units of measure are shown as appear on the display. The British and American units are diversified by using capital and small characters. 18

Please, note that the mass measure is heavily affected by the temperature and therefore with certain liquids this may cause significant measure errors. The units of measure of time may be chosen among the following values: s = second, m = minute, h = hour, d = day. (POS. 2.3) Unit of measure and number of decimal totalizes [UM.tot:dm³ X.XXX] Setting the unit of measure and number of decimals for visualized the totalizes or the volumes to batch. For set the unit of measure, position the cursor on field of the actual unit of measure; For set the type of unit, position the cursor on the blank space between the unit of measure and the numeric value; For set the number of decimal totalizes position the cursor on numeric field and choose one of the possible combinations: (POS ) Pulse value channel 1-2 and unit of measure of the total. [IMP1-2=dm³X.XXXXX] Setting of the pulse volume corresponding to channel 1-2 and of the totalizers measure units. There are three fields to fill in to set this parameter, from left to right: 1) measure unit, 2) unit type and 3) numeric value. The selection is performed by positioning the cursor on the field to be modified. To change the unit type (metric, British or American, mass or volume) just position the cursor on the blank space between the measure unit and the numeric value. When the nominal diameter is set to zero it is possible to modify only the numeric field since the measure unit stays at meter (m) or feet (ft). The possible measure units are those above described. This function is active only if the pulse emission on channel 1 has been set as enabled. (POS ) Pulse duration channel 1-2 [TPUL1-2=ms XXXX.XX] Setting of the duration of the pulse generated on channel 1-2. Its value is expressed in milliseconds and has to be between 0,4 and 9999,99. When the high frequency output is present, then the minimum value can go down to 0,04 milliseconds. ATTENTION: since the instrument cannot detect which type of device it is connected to, it is up to the user to verify the set pulse duration is compatible with the external device processing such pulses. If, for example, an electro-mechanical pulse counter is connected, then two kind of problems may occur: if the pulse is too long than the coil may burn or, if it is too short, the counter may not be able to count and eventually even cause the damaging of the output itself. MENU 3.MEASURE (POS. 3.1) Time constant [TCONST=sXXXX.X] Time constant set. This parameter affects the integrating filter making the instrument response quicker or slower, according to the set value. A higher value corresponds to a more stable but slower measure, a smaller value the opposite. The most common values are from 1 to 5 seconds. The value of this parameter has to be within the range from 0 (integral filter disabled) to seconds. The following diagram shows the response of the instrument for a flow rate variation from 0 to 100% within the T time constant period. (POS. 3.2) Acceleration threshold [SKIP THR=% XXX] Acceleration threshold set. The acceleration threshold stands for the limit beyond which a flow rate variation determines an immediate response at the output, without being filtered by the time constant. This system allows the instrument to have an immediate response in case of big variations of the flow rate, filtering (and delaying) the response to small variations. The result of that is a very stable measure, ready to follow the process. The value is set as percentage of the full scale value from 0 to 125%. If such a value is set to zero any flow rate variation bigger than 0.5% of the full scale value will immediately affect the outputs. The following diagram shows the instrument response in two cases: a flow rate variation from 0 to 10% completely absorbed by the time constant effect

20 and a variation form 10% to 100% exceeding the acceleration threshold and then immediately sent to the output. In actual fact there is always a minimum time between the measure acquisition and the outputs update. (POS. 3.3) Peak cut off threshold [PEAK THR=% XXX] Anomalous signal pick cut off threshold set. This parameter allows setting the maximum value of deviation of the actual measure sample by comparison with the average one. If the new value is higher than the set limit, than such a value is cut to the limit value. This function is used to make the meter less sensitive to big perturbations on the flow rate measure, as it may happen when there are solids in suspension in the liquid hitting against the electrodes determining a high electrical noise. The permitted values of this function range from 0 to 125 % and are referred to the full scale value. If this parameter is set to zero the peak detection function is disabled and any new measure ample will be accepted and processed as it is by the converter. (POS. 3.7) Automatic scale change enable [AUTORANGE=ON/OFF] Enables/disables the automatic change of scale. The meter may have two different working ranges in order to suit to the variable process conditions. In order to get the best results out of this function it is important that range N.2 is bigger than N.1. When the flow rate increases and reaches the 100% of the full scale 1, then the meter automatically switches to scale N.2. When the flow rate decreases again reaching a value on scale 2 equal to the 90% of full scale N.1, then the active scale is N.1 again. Allowed values for this parameter: ON / OFF. (POS. 3.8) Energy saving enable [E.SAVING=ON/OFF] Automatic energy saving function enables. This function is used when the instrument is powered by a battery or solar cells, allowing an energy saving up the The energy consumption is controlled by the ratio between the measuring cycles powering the coils and the cycles without powering the coils. When the flow rate is stable the number of off cycles is higher than the on ones, so that the average consumption is strongly reduced. If the flow rate suddenly changes, then the meter switches on a higher number of measuring cycles, in order to get a higher response time, switching off the cycles as soon as the flow rate gets back to be stable. If the flow rate varies below the acceleration threshold percentage value, then the meter goes on with off cycles, but as soon as the flow rate value exceeds such a threshold, the meter switches on many measuring cycles again. The speed the meter switches on and off the excitation cycles is different: from a constant flow rate to a variable one it is a very fast process, while from variable flow rate to a stable one such a process is much slower. Allowed values for this parameter: ON/OFF. N.B.: to optimise this function it is recommended choose a value for the acceleration threshold within MENU 4.ALARMS (POS. 4.5) Current output value in case of failure [ma VAL.FAULT =% XXX] Setting of the value of the 0/ ma current output in one or more of the following cases: empty pipe ; ADC error ; coils interrupted The allowed range is from 0 to 120% of the ma scales, 120% corresponds to 24 ma and does not depend on the selected range (0 20 / 4 20 ma). The NAMUR NE43 recommendations asks for an alarms signalling value for the current output lower than 3.6 ma (<18%) or bigger than 21 ma (>105%). It would then be preferable to set the value of 20

21 this function at the 10%, so that the current value in case of the a.m. cases would be 2 ma, allowing the following diagnostics: current < 2 ma - 5%: line interrupted, power supply failure or faulty converter; 2 ma -5% current 2 ma + 5%: hardware alarm; 4 ma current 20 ma: normal working range; 20 ma < current 22 ma: out of range, measure above 100% f.s. (POS. 4.6) Frequency output value in case of failure [Hz VAL.FAULT=% XXX] Setting of the frequency value to assign to the on/off output in one or more of the following cases: Empty pipe ; Coils interrupted ; ADC error The allowed range is from 0 to 125% of the frequency full scale value. Although there are not specific rules regulating cases like this one, it would be convenient to use the failure information as follows: 0% Hz frequency 100% f.s.: normal working range; 100% f.s. < frequency 110% f.s.: overflow, measure above the 100% of the f.s.; 115% f.s. frequency 125% f.s.: hardware alarm condition. MENU 6.OUTPUTS (POS. 6.1) Choice of the function corresponding to on/off output 1 [OUT1=XXXXXX] Choice of the function corresponding to digital Output 1. The functions are listed in the table below. (POS. 6.2) Choice of the function corresponding to on/off output 2 [OUT2=XXXXXX] Choice of the function corresponding to digital Output 2. The functions are listed in the table below.

When the pulses outputs are used, the duty cycle defines the OFF phase because the ON phase is already set with the function "PULSE DURATION"( see menu SCALE ). In this case if, for example, the duty cycle is set at 50% and the pulse duration at 50ms, the OFF phase will be the same of the ON phase. The formula to calculate the minimum time of the OFF phase and the time of total cycle is the following: T. total cycle= 100 x (pulse duration in ms)/ (duty cycle) T. OFF phase = T. total cycle - pulse duration N.B.: If the value of the function is set to 0 the emission of the pulses happens in synchronous mode with the flow rate, therefore when using the function in frequency mode, DO NOT set the duty cycle to 0. The function is active only if one of the outputs is set on pulse and/or frequency function 21
